2. P. flavum 



3. P. elatum 



4. P. Fimbria 



Labellum gradually recurved ; inner plate 

 not prominent, beginning about 

 middle and extending nearly to tip ; 

 lateral appendages of column not 

 exceeding rostellum in height; leaf- 

 lamina exceptionally short, rarely 



exceeding 1 inch 



Labellum hardly recurved ; inner plate 

 with free margins covering most of 

 surface of lamina, extending nearly 

 to tip, not prominent; lateral ap- 

 pendages of column much exceeding 

 rostellum in height; leaf-lamina 



rather long 



Labellum on a distinct claw. Lateral sepals 

 connate or free. 

 Lateral sepals connate. 



Labellum gradually recurved ; inner 

 plate with free margins copiously 

 fringed, and within it a second 

 rather conspicuous plate ; lateral 

 appendages not exceeding rostel- 

 lum j ovary elongated 



Labellum recurved at right angles; 

 inner plate orbicular-lanceolate 

 with free entire margin, extending 

 nearly to tip, no secondary plate; 

 lateral appendages column as long 

 as in P. elatum much exceeding 

 rostellum ; ovary very narrow, 



elongated 



Lateral sepals free and divergent. 



Labellum sharply reflexed about 

 middle ; inner plate not reaching far 

 beyond bend in voluminous mem- 

 branous part of lamina ; lateral 

 appendages column not so high as 

 rostellum ; ovary turgid 



The new species differs from P. elatum not only in its 

 possession of a distinct claw to the labellum, but also in the 

 shape of the labellum and inner plate, the former being oblong- 

 lanceolate, whilst the latter is orbicular in its basal portion 

 and narrow-lanceolate anteriorly; while in P. elatum both 

 labellum and inner plate are ovate. Further, the rostellum 

 and perianth segments are much wider in P. elatum than in 

 P. regium. 



4. Caladenia testacea, Br. 



A slender plant, 6 to 17 inches bigh, with a slightly hairy 

 stem and rather acute bract near middle; leaf narrow-linear 

 to oblong-lanceolate, not nearly so hairy as in most Caladenias. 



Flowers in a raceme, 1 to 5 on slender pedicels, each 

 subtended by an acute bract reaching to the base of the ovary. 



Perianth segments covered with short glandular hairs ; 

 generally dark reddish-brown, except towards tfhe base and
